In other words, during the first period, the plurality of first voltage 112 and the plurality of second electrode 114 divide into groups by display device in units of two electrodes, to determine whether there is the touch of mutual capacitance type, and during the second period, display device determines whether there is the touch neutralizing the self-capacitance type of each in the second electrode 114 for the first electrode 112.Compared with the first period, during the second period, the size of touch-sensing unit reduces, and thus, the size of touch-sensing unit is less.Therefore, the second period was suitable for sensing based on the pen touch of self-capacitance type, so that single touch can be sensed, and the first period be suitable for sensing the finger touch based on mutual capacitance type, so that touch can be sensed more.
Therefore, touch drive pattern is divided into the first period and the second period by the display device being integrated with touch-screen according to embodiment of the present invention in time, and by using the plurality of first electrode 112 and the plurality of second electrode 114, pen touch and finger touch can be sensed when not being provided for the autonomous device sensing pen touch.Further, the size for the touch-sensing unit sensing pen touch is less than the size of the touch-sensing unit touched for sensing finger, and therefore, it is possible to strengthens the order of accuarcy for sensing pen touch.
Referring again to Fig. 1 and Fig. 2, the first touch-sensing unit 300 applies the first touch scanning impulse to switch element 200, and the second touch-sensing unit 400 applies the second touch scanning impulse to switch element 200.
Such as, the first touch-sensing unit 300 can determine whether there is the touch of mutual capacitance type.First touch-sensing unit 300 can apply the first touch scanning impulse by switch element 200 to the plurality of first electrode 112 during the first period, and receives multiple first touch-sensing signal to determine whether there is touch by switch element 200 from the plurality of second electrode 114.
Second touch-sensing unit 400 can determine whether there is the touch of self-capacitance type.Second touch-sensing unit 400 can apply the second touch scanning impulse by switch element 200 to the plurality of first electrode 112 and the plurality of second electrode 114 during the second period, and can receive multiple second touch-sensing signal to determine whether there is touch by switch element 200 from the plurality of first electrode 112 and the plurality of second electrode 114.
